<pre>Display all device nodes.
   &lt;link cmd="!devnode 0 1"&gt;!devnode 0 1&lt;/link&gt;

Display all device nodes that are driven by a specified service.
Include child nodes in the display.
   &lt;b&gt;!devnode 0 1&lt;/b&gt; &lt;i&gt;ServiceName&lt;/i&gt;  
   Example: &lt;link cmd="!devnode 0 1 usbehci"&gt;!devnode 0 1 usbehci&lt;/link&gt;

Explore device stacks, device objects, and driver objects.
   &lt;b&gt;!devstack&lt;/b&gt;  List the device objects in a device stack.
   &lt;b&gt;!devobj&lt;/b&gt;    Display information about a device object.
   &lt;b&gt;!drvobj&lt;/b&gt;    Display information about a driver object.</pre>

<p>The command <b>.dml_start c:\MyFavoriteCommands.txt</b> will display the file as shown in the following image.</p><img src="images/DmlStart02.png" alt="Screen shot of DML file output"/><h2>Remarks</h2>
<p>For information about DML tags that can be used in DML files, see dml.doc in the installation folder for Debugging Tools for Windows.</p>
<p>DML output often works well in the <a href="#Bookmark1224">Command Browser window</a>. To display a DML file in the Command Browser window, use <b>.browse .dml_start </b><i>filename</i>.</p>
